Thanks,

The reason was I saw a application in VB.net where the data was displayed in a grid, more like a BOM listing. The first line would have cells like OrderNo,Partyname,Tel No. If there are a detail lines in the particular order it would appear in the row bellow. For eg it would be Item,Qty,Rate,Amount. Each in seperate cells in the row. I was wondering if it was some special Activex or some sort of HTML option.The no of detail lines would be depending on the number of rows in the order detail file corresponding to the particular order.
